My model takes website url as input and predicts its category and give the output as category name. when i am trying to pass

data = {"url" : "www.google.com"}

I get response as 400

And also my model takes list as input

For example it takes model.predict(['www.google.com'])

so in the app.py file how should I pass my function.

currently it is
`def predict():
# get data
data = request.get_json(force=True)

# convert data into dataframe
#data = data.update(data.items())
#data_df = pd.DataFrame.from_dict(data)

# predictions
result = model.predict([data])

# send back to browser
output = {'results': (result)}

# return data
return jsonify(results=output)`

Thanks.
